Product details
Control unit, Hydraulics and control module for pressurisation, degassing, and water make-up in sealed heating water and cooling circuits. Constructed in compliance with DIN EN 12828 and the requirements of VDI 4708, with CE marking. Suitable for use in noise-sensitive areas.
Functional unit comprising a hydraulic part and a Control Touch operating unit. Both are ergonomically combined in an easy-to-maintain modular floor-standing framework system made of EV 1 anodized aluminium precision sections with CE marking.
Hydraulic part:
Pressurisation is implemented using a stainless steel circulation pump in conjunction with a rugged dirt-insensitive motorised ball valve with upstream dirt trap as an overflow device. A safety relief valve is included to act as a pressure safeguard for the Variomat VG primary vessel and/or VF secondary vessel that are to be connected. The system pressure is measured with an electronic sensor. Pressure-side system connections are implemented as backed up shut-off valves. Actuation of the make-up valves is performed directly via the control unit. The dirt-resistant, motor-controlled ball valve is spring-closed without any need for an electrical supply and is electrically and hydraulically connected in the factory. All fittings are located on a rotatable base plate to enable a variable hydraulic system arrangement.
The Control Touch operating unit with TFT colour display inclusive of communications electronics is integrated in a panel-type rugged plastic housing and mounted directly on the control unit with a horizontal alignment. An optional separate and vertical wall mounting plate at maximum three metres distance from the power electronics is possible. Communication electronics comprising:
- 4,3" resistive colour touchscreen for programming, operating documentation and monitoring as well as provision of help texts for all functions
- Two RS485 serial interfaces as data and/or communication interfaces
- Serial TTL-interface with two connection terminals for connection of 2 IO-boards
- Potential-free output for forwarding of the collective message
- Two electrically isolated analogue outputs e.g. for system pressure
- Input for the evaluation of contact water meters
- Slot for a compact bus module, one SD card, e.g. for data read-out, software updates, etc.
- 230V output for connection of level-dependent makeup/degassing stations
- Main switch on housing exterior
- Pump control
- Cable management for external connections
- Mounting slot for optional modules
Control unit completely piped and wired ready for connection according to VDE regulations. System connections by means of integrated shut-off valves.
Functioning of the pressurisation in the limits +/- 0.2 bar including pump monitoring. Optimised system water degassing due to patented, fully-automatic overflow control with cycles for continuous, interval and run-on degassing. Controlled make-up, automatic interruption and fault message upon exceeding of the runtime and/or the number of cycles. Processing of the signal of a contact water meter for maximum volume limit and/or capacity evaluation of ion exchangers located in the make-up line. Documentation and control of the entire system in respect of the above mentioned parameters.

7945600 - Commissioning Cat. 1
commissioning category 1 for a standard system in the product ranges Reflexomat, Variomat or Servitec incl. primary vessel and water make-up unit by the customer service, comprising:
- without travel and departure expenses,
- Adjustment of system to the operating parameters specified by the client,
- Checking the settings and operating parameters, and the system's performance and function in the overall system,
- Fillsoft and Fillset are checked too
- All set values documented in a report.
- electrical and hydraulic connection of the control unit, the accessory components and filled supply system.
- The expansion vessels of the pressurisation station must not be filled with water.
- A sufficient supply of filling water must be provided.
While it is entirely possible for customers to put a recently purchased system into service themselves, there are a number of reasons why commissioning by Reflex is a better idea.
- Certainty that the system is set up for optimum operation
- Excluding of possible damage due to incorrect commissioning thus reliability and avoidance of time and costs for downtimes
the service can take place within the local country inside about three weeks, internationally within about six weeks after placing of the corresponding order.
Services provided by Service are net! The price does not include any site waiting times or work arising from improper installation or improper condition.
Programming of the expansion and bus modules does not form part of commissioning. Programming is billed separately based on time and expenditure.
7859100 - Master-Slave Connect
Expansion option for Variomat pressurisation systems with Control Basic or touch controller.
For balanced, optimised operation of up to 10 Variomat/Variomat Giga in one network. All connected devices must have this control option available.
Separation between devices <1,000 m.
8997705 - I/O module VS
Expansion for controllers of Reflexomat, Variomat and Servitec control units.
With two isolating amplifiers for the pressure and level sensing signals. Six digital input contacts and six floating output contacts are used to process messages and alarms. Everything in its own plastic housing for direct integration in the corresponding control unit or optionally for wall mounting.
Individual description:
- Digital input: -freely programmable, 6 off, 3 off as NC contact, 24V self-potential, default configuration e.g. for external temperature monitoring, min. pressure signal, manual make-up, and 3 off as NO contact, 230V external potential. Default configuration as NO contact, e.g. for emergency shutdown, manual mode pump/compressor, manual mode overflow facility.
- Digital output: -freely programmable, 6 off. As floating change-over contact, default configuration e.g. for signalling of water make-up faults, minimum pressure undershot, maximum pressure exceeded or manual/stop operating mode.
All the above contacts can be freely configured by Reflex service according to the available information.
Installation: Plastic switch cabinet housing can be inserted in the provided mounting slot of the control unit, as an alternative to on site wall mounting or installation in other switch cabinets.
The wiring to the control unit is likewise performed on site.
9118042 - bus module Profibus DP Touch
Bus module for conversion of the information such as operating status from the control interface of Variomat, Reflexomat or Servitec as compact modules usable with the Control Touch controller, into the data telegram.Direct integration on the control PCB of the Control Touch. No additional assembly is necessary. Connection to Touch Control via plug socket.Installed in the controller housing of the Control Touch as an integrated extension module. On the Profibus side an RS 485 interface is available. Remote control of the following functions and parameters from higher level building management system:
